Fig. 18: High Density Terminals

The Bus Terminals from these series with 16 connection points are distinguished by a particularly compact

design, as the packaging density is twice as large as that of the standard 12 mm Bus Terminals. Massive

conductors and conductors with a wire end sleeve can be inserted directly into the spring loaded terminal

point without tools.

Ultrasonically "bonded" (ultrasonically welded) conductors

Ultrasonically "bonded" conductors

It is also possible to connect the Standard and High Density Terminals with ultrasonically

"bonded" (ultrasonically welded) conductors. In this case, please note the tables concerning the
